Solves the same problem as #5408. |

I agree; I’ve also found this to be the reason, and I think this change is reasonable. However, should we keep this JIRA ticket open, or should we create a new one? |

IMO we should merge this patch, but as a "Minor: ..." commit, unrelated to CALCITE-7928 because it does not address the root cause of the planning time explosion. |

I will resubmit the test fix as a separate PR. |

Changes Proposed
I have re-enabled the query but disabled (for this test only) a Volcano rule which is executed about 2 million times for optimizing the program generated by the decorrelator. With this change optimization is much faster.
